I've seen tons of programs not check read return value yes but these also have no idea what O_NONBLOCK is so I'm not sure how realistic a use-case that is? The alternative I see would be making pipes go through the server as I said, but that would probably mean another mount option for this; pipes work as local pipes like they do in nfs currently. -- Dominique
